In certain vertebral stabilization systems it is desired to secure a longitudinal member along one or more vertebral levels of the spinal column to provide stabilization to the vertebrae. Fasteners that secure the longitudinal member to the vertebrae can require significant alteration of the bone. The fasteners can also project from the bone into the adjacent tissue in order to accommodate the components of the fastener and the longitudinal member. Fasteners can also require the handling and placement of multiple small components to engage the longitudinal member to the fasteners. While various vertebral and skeletal stabilization systems have been developed, a need remains for low profile stabilization systems that facilitate and expedite engagement to the bone and engagement of the longitudinal member along the bone.
